Welcome!
This is a short presentation of softwares (PC, Android) and pdf-documents made by Jan Lindström.

Excluding Pdf-files, are now the files to be downloaded from here, hosted at Koofr.net (see links below). When you click on a link, will a list of files appear. Mark in front of one (or more), and hit the Download-button.

The programs are free to use, if you follow their simple licenses.

PC

The Windows-versions can be run on other platforms (Linux, Mac OS X, BSD and Solaris), with the help of Wine. All packages for Linux and Windows includes two versions (32/64). Linux-programmes are built and tested on Debian and Ubuntu.

Distribution exists as compressed zip- or tar.gz archives. The softwares need no installation, and have small demands on the systems. They use portable built-in graphics and rendering of text. Linux-variants depends only on the X Window System (usually called Xlib, X11 or only X).

ANDROID

Most programs exists also as Android-apps. For now are they not published (uploaded to a market). Be absolute certain of what this means. You can without problem find information about sideloading, unknown sources and independent app stores, on the net. From Android 8.0 is it possible to install single apps with sideloading, in a better way. If you lack the proper knowledge, and/or trust to these apps, use the PC-versions instead (if possible).

The apps have no possession to the rest of your system. They will not connect to the internet. Should work with Android >=4.1.

Metal spinning can be seen as an spectacular, hard-learned, and quite old technique, this to form a round sheet of metal. afTRYCK is a software that describes it. Read more HERE.

HULTABY version 2.1

Hultaby gives you in 3D, Hultaby castle (or maybe more accurate, residence), in my view of its 14th century apperance. Today it´s a ruin, just outside the city Vetlanda, Sweden. Read more HERE. The software exists for Linux, Windows and Android. This version includes updated graphics.

SE-AEA

A software that make a presentation to an autogiro model Cierva C30. This with 2D- and 3D-images, and text both in English and Swedish. Read more HERE. It can be downloaded for PC (Linux, Windows), and for Android.

J22

FFVS J22 was an Swedish WWII fighter- and reconnaissance-aircraft. It was constructed because purchases abroad failed. SAAB was at this time fully occupied with their own manufacturing. The J22 was therefore a project run by the Swedish Airforce (Airboard) itself.

The aircraft are here presented in 2D and 3D images. Text are in both English and Swedish. See more HERE.
